Has anyone done this or know where i can find instructions?

In a previous post of mine - TDV8 Coolant Leak Hose Name - it looked to be the hose leaking as dried coolant was evident around the 90 degree hoses, but replacement of the hoses did not cure the problem for long. With an inspection camera i can see coolant in the valley and crusty coolant around the Thermostat housing area but cannot see the exact location, as there is very redistricted access.

Searched heaps online cant find much info about thermostat leaks.

I was going to do a detailed post about the very same job that I have just done, but for some reason all but one photo is on my phone.
Here is a link to what needs to be done to get to the thermostat housing, which is the last thing to be removed after everything else is removed first.

I hope Edfors doesn't mind me using his detailed post.
You can see the thermostat housing just below the oil filter housing in Edfors' first photo.
Here is the last photo with the housing removed from our vehicle.
Notice the antifreeze residue around the filter housing, etc.

That's great

Apparently it's not an uncommon problem and the housings can split.

Thanks Steve

Hi Steve, any others gaskets/parts you think I should order for this job other than the thermostat housing and elbows.

Will order parts from the uk

Cheers Paul

There is a whole rake of gaskets that you could order, egr gaskets mainly, but I didn't bother.
Some are quite reasonable, others are extortionate.
The egr gaskets whilst having a black coating on them are made of very thin steel. I cleaned them up along with the surfaces that they fit to and all is well, no leaks that I can detect.
Tools that will help are a 1/4 inch drive socket set with plenty of extensions and a 1/4 inch knuckle unit for those hard to reach awkward places.

Looks like it is starting to let go on that welded seam.
Ours went here (circled).

Good Steve,

Waiting for the housing to arrive, slowly dismantling in the meantime. I removed the egrs to clean while at it.

Cheers Paul

Paul,

What was the condition of your EGRs ?? Regards

i had mine done last year as it was cracked by my mate took him a few days and did a few other bits while stripped  _____________________________________________________

That looked to be leaking worse than ours seeing all that crud around the oil filter housing.
With the state of the boss where it fits into the block, I'm surprised that it wasn't leaking from there.

It's possible there was more than one leak, I dis had a slow leak for over year which I couldn't find as I'd say as it leaked the heat from the engine evaporated the water leaving the coolant deposits. When it got worse that may have been the original leak or maybe a second leak. With the second leak sometimes I could see coolant under the car.

I used an inspection camera and looking back from the oil filter could see coolant deposits on 90 degree coolant hoses.

I originally thought it was the 90 degree coolant hoses leaking so I replaced those and for a few days it was fine, but then it leaked again.

I then heard the housings can be a problem so after an hour with the inspection camera poking through holes here and there I eventually found where I think the leak was on the housing. The split in the thermostat housing may be leaking more under certain conditions eg hotter/more pressure.

The boss was a surprise, when I new I had all bolts out I had to move the housing side to side and lever up which is why it broke but it could not be rotated so I'd say breaking was the only option.

Seeing how much it was welded/ fused to the boss, as it also needed to be gently persuaded out with a crow bar, i don't think it would ever of leaked.

I got down to 1200 grit and smoothed it as much as possible but their was still some pitting I think it will be ok.
